NOTE: There is no warranty on exhaust pipes and mufflers with regard to any discoloration. Discoloration (blueing) is the result of tuning characteristics, cam timing, carburetor jetting, overheating, etc., and is not caused by defective manufacturing. See the CHEMS/LUBES section in the back of this catalog for products that will help prevent or remove blueing.

NOTE: Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the exhaust manufacturer directly with questions regarding any modifications that may need to be made during. or after, installing their product. If a jet kit or fuel processor is recommended, see the FUEL/INTAKE section

i had tried other pipes on my bike but they turned blue almost immediatly just before the baffles, was not happy at all since the carb was re-jetted to pipe manufacturers specs(obviously to lean) but these 3" pipes are the right ticket, quiet when i'm jus cruizin but louder than heck when i get on it, a lot of guys want me to run tailgunner cuz their so loud,,,, i get on it a lot,.. lol

They are loud. Not a lot of options for the C109 unfortunately, but these work just fine. I will have to pick up an injection tuner, but i do like them. When pinning the throttle they let everyone know with in a couple zip codes you are in the area. At cruising they mellow out nicely to a good growl.
